SPECIFICATION forming part of Letters Patent No. 705,752, dated July 29, 1902. Application filed December 5, 1901- flerial No. 84,783. (No model.)

To all whmn it may concern.-

Be it known that I, GEORGE GUN'IZ, a citi zen of the United States, residing at Brooklyn in the county of Kings and State of New York, have invented certain new and provements in Soldering-Irons; andI do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to soldering-irons; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a plan view of the soldering-iron, showing the handle in section. Fig. 2 is a side view of the socket. Fig. 3 is a cross-section taken on the line at a; in Fig. 2.

A is the copper head of the soldering-iron, provided with a socket a at one end. This socket has tapering sides I), and it is wider at its end b next to the head than at the other end.

O is the shank, provided with a plate 0 at one end. This plate has tapering sides and is broader at its extreme end, so that it may readily be dropped into engagement with the socket a of the head.

D is a bolt which passes through the plate movable, and other heads of different size and weight may be secured to the shank in a similar manner.

The shank O is provided with projections e, which are struck up from its surface with a suitable tool, and these projections form an abutment or stop for the handle.

E is the handle, provided with a chamber f of larger diameter than the shank, so that an air-space is formed around the shank.

G is a collar of asbestos or other similar material which is a bad conductor of heat. This collaris insertedin one end of the chamber f around the shank, and it has a flange g, which bears against the end of the handle.

H is a metallic ferrule or cap which encircles the end portion of the handle and incloses the flange g and bears against the prouseful Imjections or stop 6. shank is screw-threaded, and I is a nut which is let into the end of the handle and which engages with the screw-threaded end t, thereby securing the shank in position and drawing the projections e tight against the end of the ferrule. The air-chamber and collar prevent the heat of the shank from destroying the handle.

* What I claim is 1. In a soldering-iron, the combination, with a removable head provided with asocket whichhas tapering sidesand is broadest at its end next to the head, said socket being open on top and at its narrow end, of a shank provided with a plate which fits the said socket, and a fastening device which secures the said plate in the said socket, substantially as set forth.

2. In a soldering-iron, the combination, with a shank provided with a head at one end and a series of projections struck up from its sides, of a handle which abuts against the said projections, and means for securing the said handle on the shank, substantially as set forth.

3. In a soldering-iron, the combination, witha shank, of a handle provided with an air-chamber around the shank, a collar of non-heat-conducting material encircling the shank and inserted in one end of the said chamber, and means for securing the shank in the handle, substantially as set forth.

.4. In a soldering-iron, the combination, with a shank having a stop for the handle, of a handle provided. with an air-chamber around the shank, a collar of non-heat-conducting material inserted in one end of the said chamber and provided with a flange, a ferrule which bears against the said stop and incloses the said flange, and means for securing the shank to the handle, substantially asset forth.

In testimony whereof I aifix my signature I in presence of two witnesses.

GEORGE" GUNTZ.
